Objective: The purpose of this study was to evaluate the accuracy of algorithms for the asment of gestational age with the use of the last menstrual period and early ultrasound information. : Last menstrual period reports show digit preference, as gestation 2.
Misclassification of births as postterm was more common in younger women, those of nonoptimal prepregnancy body weight, cigarette smokers, and women who reported last menstrual period using preferred dates of the month. Conclusion: Last menstrual period estimates of the duration of gestation are subject to both random error and a systematic tendency to overstate the duration of gestation, most likely because of delayed ovulation.
